摘要

Two new Ti (IV) complexes of the type [(OCHRCH2N-2, 6-Me2Ph) Ti (NMe2) 2] 2 (where R= H, or tbutyl) have been synthesized by protonolysis of Ti (NMe2) 4 with the corresponding N- substituted amino alcohol ligand. The two complexes were studied as Ziegler–Natta type polymerization catalysts in the presence of an excess of methylaluminoxane (MAO). It was found that ethylene polymerization activity for both catalysts increased by increasing the ...
